DX340 iBasso developed Discret DAC, Easily replaceable batteries, Amp Modules! ***New firmware on 1st page. v1.04 local update. ***

It's almost too bright, reduced brightness to 20% on mine.

Btw for those who know how to use ADB, the following command significantly speeds-up performance (some say by ±15%). My DX340 definitely boots faster now.

# adb cmd package compile -m speed-profile -f -a
(Takes about 3 minutes.)

Thanks!

On Windows 11 I think you have to put "shell" between adb and cmd.

so

" adb shell cmd package compile -m speed-profile -f -a "

Yep, typo!

Very enjoyable session with the DX340 and Denon D9200 this afternoon, blissful experience!

Nice to see you driving cans off the DX340!

I put a high storage battery pack on the 340 for the USB C input. Slightly warmer sound, everything else preserved. Nice.

But with around 300 hours, I like the way the 340 is sounding with the C input from charger. I asked and once the batteries are charged the C input takes over and you aren't running on the internal batteries.

Using the 12 volt linear power supply, ridiculously large but excellent AC to DC conversion with a lot of super caps and the regulator is the special sauce for this converter.

I am using some sensitive IEMs and zero background sound/noise. None. I thought I had a tiny bit but it is my ears, same sound with or without the player on and the IEMs in my ears or not in my ears but so low, just glad my ears are still really good. Something I inherited from my mother. As she aged, her hearing got better to the point where it was a distraction for her and then with dementia, well not good. But that is another story.

The versatility of the 340 is remarkable. Used it with the Cayin Soul 170HA with GZ34 metal base rectifier, best input tubes and of course the KT170. Superb.

On bass, I hear nothing lacking. Rumble, mid bass and upper bass all there but it does go in and out as the unit burned in, or burns in and the burn in time is longer for the 340, from my experience, than many other daps. One hundred hours is a start but you have not reached the finish line. And compare it to something of a known sound to verify this, for those who do not believe in the sound changing as caps form, and the rest of the components, batteries, develop their mojo.

Which IEMs? Curious as I get mild background hiss with Campfire DarkStar IEMs using the 3.5mm output on low dac and low amp gain. You can hear the output mute (dead quiet) and unmute (hiss) after clicking play or pause on a track, then hiss when the song is quiet and playing.

With these IEMs I listen at 11 to 15 volume (quite loud at that point) on low dac and low amp gain).

But, I REALLY enjoy the DX340 with Darkstar and the slight hiss does not bother me.

Just wanted to share another experience point so people don't have unrealistic expectations about how quiet the DX340 is for some IEMs. Campfire are notoriously sensitive so grain of salt and all that. (I also listen at night when the ambient noise levels are very low. So, minor stuff like this stands out to me. I wouldn't notice this during the day).

What's very cool is I also plugged in my JAR650, cranked all settings to high gain, and was blown away how well they are driven by the DX340. I did plug in the external power supply as well and was pleasantly surprised it did indeed improve things. This is a really versatile device! I'm excited to try out the other amp modules when they release.

I just did the ADB commands for faster boot and debloating, player really does respond faster in Android mode now! Faster boot as well.

Has anyone rooted the DX340 yet?

Wait, did you mean the external battery will feed the DAC function instead of charging it ?

I also have mild hiss with the Campfire Audio Clara. I know Campfire IEMs are quite sensitive so I wouldn't entirely blame the DX340, but the background is not as "dark" as the SP3000M or N6iii and as a low volume listener I do find the background noise to be a little distracting at times. It is mostly more apparent to me when I listen in the morning with fresh ears as opposed to later in the day/afternoon.

I think we just found another areas where D16 is better

Yes, a nice Rav Power battery pack. It charges fast and has USB C and A. 20,000 mAH and up to 20 volts output.

OK, so regarding the topic of the waterfall hissing. Just as a few people mentioned above which is very helpful, this is a function of DAP+IEMs. You can test DX340 with a dozen IEMs in your collection and will hear a pitch-black background if those are not sensitive IEMs. I typically used Aroma Jewel for my sound analysis, and there is no hiss whatsoever with DX340. But, as soon as I switch to Campfire Audio Andromeda or Solaris, or Vision Ears VE10, the waterfall hissing is quite noticeable. Those are sensitive hybrid IEMs with a particular internal crossover design that yields this waterfall type of hissing with some DAPs. A simple test is to hit Play and lower the volume to single digits or use a less-busy test track like Agnes Obel's "The Curse" where in the first 30sec of instrumental intro you can hear the background loud and clear. Again, this is relative to a specific pair-up.

But, once I changed the AMP gain from High down to Low, the waterfall hissing with these sensitive IEMs was attenuated significantly to my ears. That is how I would recommend a pair-up with sensitive IEMs and DX340/amp15, using high DAC gain and low AMP gain.

Furthermore, when talking about stronger or more relaxed bass performance, it is also relative to the pair-up synergy and comparison to other sources using the same pair of IEMs or headphones. Just another 2c, when sharing such impressions or concerns, it would be very helpful to mention what IEMs/headphones you are using and relative to what other sources you find something warmer/brighter/bassier, etc. That will put it in a better content instead of just saying the source is U-shaped or lacks a bass We hear the sound relative to IEMs or headphones connected to the source and how the source shapes/finetunes their sound signature. Of course, we do hear things differently, use different IEMs, have different hearing health (some might have tinnitus louder than the hissing ), etc. I got pinged by a few people in the last couple of days, asking me why they do or don't hear DX340 the way others describe it in this thread. That is just the way it is Because someone hears more or less bass or hissing, doesn't mean you will hear it the same way, especially when using different IEMs or headphones, or just because you have a different hearing ability. People share their personal experiences in this thread, relative to how they hear the sound with their particular IEMs/headphones. I wouldn't take it with a grain of salt because that is just how they hear it, and it doesn't mean they are wrong or that you will hear it the same way. Btw, CanJam NYC is just around the corner where you will be able to test it yourself at Bloom tables. I will bring mine as well for anybody who wants to hear it.

Yes, Clara is hissing a little, I use one of these ifi adapters. Dead silent with it.

 

[Whitigir]

How come flagship pricing buds has so much pickiness ?

Actually...I take it back....if it isnt 16k...it isnt flagship

 

[twister6]

Yep, that is another solution, using the ifi iEMatch adapter which works like (but not exactly) an impedance adapter. However, because of the impedance change, it could affect the tonality of your hybrid IEMs But, for sure, this is a solid solution!

The bass from the phone out is still my biggest and basically only gripe of the DX340 so far. It's just way too light for me and lacking in weight, texture, and depth imo. I love how detailed and tight it is, but I would not suggest this DAP for IEMs that are light on the mid bass as is as they can sound a tad too anemic down low. With that said, I usually swap to the SP3000M or N6iii when I am wanting for heft in the lows.

I can't wait to see what the newer AMP cards bring!

I’m using IE900 and get plenty of bass and sub bass with mine (as long as I’ve got the seal sorted).

Yes, I keep the player on High Gain/Super Gain even on my IEMs becuase after some burn in the tonality was no longer peaky as before.

me too, high/5 using IE900.
